Advice Request Maximum number of Extensions on Firefox & Chrome?

[Ink]

Anyone know?

Edit:

1. Are there limits set by Mozilla or Google?
2. Is the limit hardware dependent?
3. What happens if 50% or more of the installed extensions conflict?
4. Are there any security or privacy risks?
5. How does it affect the stability of Chrome vs Firefox?
6. How many can be sync'd?

I know people who use at least a dozen, lord knows why. I guess you can use as many as you like as long as you don;t have several who do the same job or until your browser comes to a standstill. I use 4, good enough.

I use about a dozen on Firefox, but many are to replace functionality that was lost in the Web Extensions changeover. uBO and Violentmonkey are the main ones, but I also use a screenshot tool, download managers, and exts to restore things like copy/paste, right-click menus, etc.

I don’t think I’ve ever used more than 4 or 5 on either. Currently use 3 or less on FF, and 4 on chrome.

Are there any security or privacy risks?

Definitely yes.

It appears that there is no limit for either browser. I've got 20+ extensions installed in Cent (Chromium based) with no issues.

I use 20 in my Ungoogled Chromium for it comes with bare protection.

16 in Brave for I disabled its built-in security/privacy protection and added mine. Similarly, equally as many for FF

Think of your browser as a first line of defence against the below and ask yourself how many extensions you need for protection. Since you are NOT going to be anonymous don't worry about being unique on the net.

- ads & ad trackers
- malicious sites
- analytics (beacons, pixel etc)
- browser fingerprinting e.g. mouse wheel/speed etc besides those listed(and protected) in ScriptSafe and Trace. Also, cross-browser fingerprinting for hardware e.g. screen resolution/GPU/CPU/RAM/audio context, ultrasound cross-device tracking (uXDT)
- social widgets
- microphone hijack
- WebRTC leak
- unwanted cookies (e.g. cookieless cookie (aka Etags, supercookies, evercookies, zombie cookie), super HSTScookies, HTTPS cookie, zombie cookies etc)
- webbugs
- clickbait links
- in-browser cryptojackers
- browser hijackers
- browser lockers
- phishing and online scams
- PUPs, toolbars and pop ups
- overlays
- CSS (Cascading Style Sheets)
- anti-XSS
- zero-width Unicode characters
- clickjacking
- CDNs (Content Delivery Networks)
- redirects
- session replay scripts
- spoofing/randomizing user-agent/timezone/header(etag and referer)/geolocation
- clean URL tracking
- WebGL
- ultrasonic tracking
- browser-based rootkits and browser-based botnets
- DNS rebinding attacks
- JavaScript-based side-channel attacks against leaks from CPU/RAM
- other web annoyances

but I also use a screenshot tool

But Firefox already has a screenshot tool built in.

You don't need protect against all your listed stuff as not everything is dangerous.
Also most can be easily blocked with JavaScript disabled which e.g. Edge provide natively.

Anyway nice list

It's true if you disable JS then most will be blocked including your images, videos etc on the webpages as well

But Firefox already has a screenshot tool built in.

I use Save Screenshot – Get this Extension for Firefox (en-US) because it offers much more than the built-in tool, like full-page screenshots extending beyond the viewport. (I still find the built-in tool handy for quick, small-area grabs from Twitter, etc.)

 

[SeriousHoax]

like full-page screenshots extending beyond the viewport.

The built-in tool has these features too

 

[Deletedmessiah]

I use 13. Yeah it maybe some kind of security risk to use this many but all of them have improved browsing experience in ways. ublock origin is the only security extension though if it counts. Edge's smartscreen and tracking protection + ubo is more than enough for me for security.

I didn't know that - thanks for the tip

I do not think there is a limit to use of extensions, but you have to limit yourself, it is not good to have so many extensions, you just have to have the essential ones, for many reasons.

1) for privacy.
2) due to conflicts between extensions.
3) because they slow down navigation.
